The AirTAC GFR600-20LF2WG AirTAC Filter Regulator G3/4 Low-Pressure is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-20LF2WG is a filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This size 600 unit has a G3/4 (BSPP) port, a 5 um filter element (the finer W grade; 40 um is the standard grade), a differential-pressure drain and an embedded square gauge reading in psi. It is the low-pressure regulator type, rated to 1.0 MPa (145 psi) maximum inlet pressure and operating from -5 to 70 C (non-freezing), with an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options including manual or automatic drains, 5 um or 40 um elements, square or round gauges with MPa, psi or bar scales, PT, G or NPT threads, and an optional reverse/check valve. The exact adjustment range of this low-pressure type is not published; we confirm it, along with flow figures from the datasheet, on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeding spray guns and booth tooling on a paint line, where the air supply is filtered to 5 um and held at the low, stable pressure that finishing work calls for.
Conditioning and regulating the air feeding cylinders and grippers on a carton-forming and sealing conveyor, with the square gauge giving operators a local pressure readout.
Supplying finely filtered, regulated compressed air to instrument benches and pneumatic test rigs, where the 5 um element protects sensitive downstream equipment.
Size and port step up with required flow: 200 through 600, ports from 1/8 to 1 inch; this unit is size 600 with a G3/4 port. Drain choice is differential-pressure (the default, fitted here), automatic (A) or manual (M). Filter grade is 40 um standard or 5 um (W) as fitted here. The gauge is the embedded square type (psi scale here), with an external round gauge optional in MPa, psi or bar scales. Thread: PT is the standard; G and NPT are order options. Bracket included. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR family as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the relevant flow figures from the datasheet on request.
L marks the low-pressure regulator type. Its exact adjustment range is not published in the catalogue data we hold, so we confirm it on request. For comparison, standard (non-L) GFR units with a differential-pressure drain like this one adjust from 0.15 to 0.9 MPa (20-130 psi).
